Designated "A Landmark of Federal Architectural Significance" and located on St. Petersburg's main thoroughfare, The Atrium at Nevsky 25 - a Class A office building - assembled private and public expertise to preserve the building's architectural integrity while creating a symbol of the city's commercial rebirth. Retailers occupy the first floor, offices are on floors 2-5 and an existing courtyard was enclosed with a skylight and completely refurbished to facilitate circulation within an existing new space. Walls and floors have been strengthened to Western standards and new installations including triple-glazed windows, lobby flooring of patterned granite in the style of 19th century Russian palaces, advanced heating, ventilating, air-conditioning and security systems have been installed. To restore the building's original roof line, a top floor, not part of the original structure, was demolished and replaced with two new floors under a slanted roof. For maximum impact these floors were oriented towards a new glass-enclosed central atrium that had previously been the courtyard. The light weight framing of the floors offered an extra benefit: open and efficient office space.

The Atrium at Nevsky 25 was designed to the highest technical specifications and is the only operating building in St. Petersburg with such advanced and sophisticated systems.

Since its opening in November 1997, the Atrium has won international and domestic recognition, including first prize for FIABCI Prix d'Excellence 2000 in the Office/ Industrial Category as well as the 1999 Russian Federation Award for Architecture.
